55B29

The 55B29 filter element (air-oil separator) is a high-efficiency coalescing air/oil separation device designed specifically for industrial screw air compressors.

Multi-layer coalescing filter material structure: The inner core filter layer is composed of ultra-fine glass fiber (typically HV glass fiber from the US or Lydall glass fiber from Germany). When airflow passes through the filter element from the inside out (or from the outside in), fine oil droplets coalesce into larger oil droplets upon collision with the glass fiber and fall into the recovery tank by gravity.

• Thickened anti-corrosion metal frame: Both inner and outer frames adopt high-quality thickened stamped galvanized steel plates or stainless steel, featuring excellent compressive rigidity. The filter element will not collapse, deform or rupture even under instantaneous airflow impact or high pressure difference.

• Integrally formed large oil-sealed flange: A wide outer rim flange is equipped at the top, which delivers superior mechanical sealing performance and prevents any short-circuit air leakage at the junction between the oil-gas barrel and the filter element.

• Dual anti-static design: Special metal conductive strips (static pins) are fitted on the sealing gasket. This structure can promptly conduct static electricity generated by friction of high-speed airflow, completely eliminating the safety hazard of combustion and explosion inside the oil-gas barrel caused by static sparks.

Key Advantages and Value

• Extremely low pressure drop for energy saving: The initial pressure loss is controlled at ≤ 0.02 MPa. Lower resistance means the air compressor main unit does not need to consume extra electric power to overcome the resistance of the filter element, which can save enterprises a large amount of electricity costs during long-term operation.

• Ultra-long service life and reduced maintenance costs: With standardized maintenance and high-quality lubricating oil used, the designed service life can reach 4000 - 8000 hours, effectively extending the maintenance cycle of equipment and reducing the frequency of shutdown maintenance.

• Protection of downstream equipment: The oil-gas separation efficiency as high as 99.9% can greatly extend the service life of downstream precision filters (line filters) and adsorbents in adsorption dryers (such as molecular sieves and activated alumina).
